Katy Perry will headline the pre-match entertainment at this year's AFL grand final.
With a plethora of hits to choose from, the pop star will have to whittle her setlist down to just a handful of tracks.
Here are the details we know so far:

What songs will Katy Perry sing at the AFL grand final?
Perry's exact setlist won't be made public, but we've already been given some hints as to some potential inclusions and exclusions.
Channel 9's Tom Morris has reported the singer will perform five songs.
The 39-year-old is understandably keen to promote tracks from her new album '143', although the AFL reportedly pushed back, with a preference she plays her better-known hits.
Per News Corp, an agreement has been reached that just one song from her latest album will be performed. Possible options include 'WOMAN'S WORLD' and 'LIFETIMES'.

As for the other four songs, there is no shortage of certified hits to pick from.
'Last Friday Night (T.G.I.F.)', 'Dark Horse' and 'Firework' are just some of her songs that have surpassed one billion streams on Spotify.
Perry could also pull from other popular tracks such as 'Roar', 'I Kissed A Girl', 'Hot n Cold', 'California Gurls', 'Teenage Dream' and 'Wide Awake'.
There was some doubt around her performing 'Roar' due to the Brisbane Lions' participation in the grand final though, although that is unlikely to factor into the setlist construction.
"I have to cut my song 'Roar' out of my set because it's not fair – that's what everybody says," Perry said in an interview with Fifi, Fev & Nick.
However, she quickly reversed that claim, stating: "I'll play it".
Which artist is singing with Katy Perry at the AFL grand final?
Perry has revealed that she will be joined on-stage during her performance by a female Australian artist.
"There’s going to be a surprise performance of a favourite Australian artist that I look up to," Perry told Channel 7's Sunrise.
"She will be singing a little bit with me, I’ll be singing a little bit with her. I’ve been sworn to secrecy, locked up, chains, all of it."
The reference to 'chains' has some fans believing it could be Tina Arena.
Who else is performing at the AFL grand final?
A strong supporting cast will be in place for Saturday's pre-match entertainment program.
ARIA Award-winning artist Christine Anu and singer-songwriter Zipporah Corser-Anu will feature at the MCG, while Mike Brady will also be on hand to perform the iconic 'Up There Cazaly' track.
Singer, actor and athlete Cody Simpson will sing the Australian National Anthem.
